HIGHPASS / LOWPASS / NOTCH FILTERS

Print

Encore offers several analog filters for noise reduction and anti-aliasing applications. Unity gain in the passband is standard, although the Model 721M adds a switch-selectable gain of 1, 10, or 100. Response can be configured for Butterworth or Bessel based upon request.  Switch-selectable frequency cut-offs are typically specified by the customer.

For powerline noise reduction on ±10V signals, Encore offers single channel, notch-reject filters set to 50 or 60Hz, in a compact DIN-rail package.
